The Model Answers Series are revision aids for Grade 10 and 11 secondary students who are studying for their CSEC® examinations. Each book in the series comprises of five sets of 60 multiple choice questions similar to those that will appear on the actual examination paper together with answers and comments about these questions. Each book also contains complete answers to the questions set on the June examination papers in that subject between the years 2006 and 2010. In addition to these answers explanations are also given where appropriate so you don't just get the right answer but, more importantly, you can see how it has been worked out! The books have been designed to help students improve their chances of success in their forthcoming examination. They include a chapter on how to revise, how to draw up a revision timetable as well as how best to approach the examination on the actual day. There is advice from experienced examiners on how to avoid throwing away valuable marks through making avoidable mistakes as well as how to gain extra marks by writing down answers in the clearest possible way. The Model Answers Series should be used by students in collaboration with the corresponding CSEC® past examination papers in each subject.
